After the producers of Sriracha warned in a statement that a shortage of its product was 鈥渦nprecedented,鈥 one Alberta restaurant worries about how customers will react to missing out on their favourite spicy sauce.

鈥淚t鈥檚 mixed with the pho, you know? It鈥檚 really good when you mix the Sriracha in,鈥 said Rose Tan, manager of Phobulous Vietnamese Restaurant in Edmonton.

鈥淎ll Vietnamese restaurants, they have Sriracha. 鈥 If it鈥檚 going to be long-term, it鈥檚 going to be not good for the business.鈥

Huy Fong Foods, one of the world鈥檚 largest producers of the Asian hot sauce, attributes the shortage to droughts in Mexico and the southwestern U.S., causing a crop failure of the chili used in Sriracha. The company said it has been forced to stop production on the popular hot sauce, and that orders for Sriracha filled after mid-April won鈥檛 be filled until September.

鈥淲e can confirm that there is an unprecedented shortage of our products,鈥 the company said in a statement to CTV National News.

Huy Fong Foods said it hopes a better chili crop in the fall will help boost production, but as with many food products these days, a short supply could mean an increase in price at the grocery store.

Experts say the unpredictable impact of climate change means unexpected shortages of products like Sriracha could continue to happen with other products.

鈥淭his is part of a bigger problem that鈥檚 starting to become a much bigger reality for most people,鈥 Ellen Goddard, an agricultural economist at the University of Alberta, told CTV National News.

Low yields of mustard seed so far this year are also expected to lead to a shortage of the popular hamburger and hot dog condiment.

In the meantime, Tan said she has a plan to stock up before the red sauce becomes even more difficult to find.

鈥淲e need to order extra, because customers like Sriracha,鈥 she said.

Tan said the restaurant is stocking up on Sriracha and hoping the supply lasts through the shortage, but she also said she has a back-up plan.

鈥淚n case [of] no Sriracha, I鈥檓 going to make my own chili sauce,鈥 she said. 鈥溾 Because customers like spicy."
